To provide transaction consistency, Message Queuing logs transaction status changes and incoming messages to a log file (QMLog), and then creates a checkpoint that is written to a separate file. The checkpoint file contains version information, and the QMLog is updated to refer to that version of the checkpoint file as being the current checkpoint.

During initialization of the MSMQ Service, there is a recovery phase for transactional messages where the QMLog file is read. It contains the version information for the most current checkpoint entry in the checkpoint files and then uses the current checkpoint file to perform recovery of transactional messages.

If there is a failure between the time that the checkpoint file was created and when the QMLog was updated with the new version, the QMLog file refers to the earliest checkpoint file version and recovery fails.

Message Queuing uses several checkpoint files to maintain consistency. These checkpoint files are used to perform recovery of transactional messages.

Event Details

Product:

Windows Operating System

ID:

2053

Source:

MSMQ

Version:

6.1

Symbolic Name:

EVENT_ERROR_QM_INIT_INSEQ_FILE

Message:

The incoming sequences checkpoint file failed to initialize. The file MQInSeqs.lg1 or MQInSeqs.lg2 in the Msmq\Storage folder is corrupted or absent. Error %1: %2

Resolve

Delete incoming sequence checkpoint files

Checkpoint files must be available for Message Queuing to function properly. To resolve this issue, you must delete the incoming sequence checkpoint files, as well as the QMLog file in the Message Queuing storage directory. This can result in some messages being duplicated. However, this will get the service running as soon as possible and usually without data loss.
